How do I make him mine?

There's a guy I met through a friend and we've been talking for about 2 months. We hooked up and he told my friend he likes me. He calls me just about every night before he goes to bed. And usually text me everyday but the thing is he told one friend that he likes me but doesn't want a girlfriend right now. What's the deal? I really like this kid but how do I get him to ask me out? How do I stand out from other girls?
